To all whom t may concer-r1,.-

Beit known that I, ANDREW GULLrcKsoN, a citizen of the United States,residing at Gatzke, in the county of Marshall and State of Minnesota,have invented certain new and useful Improvements in Plows; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same. Y Y

My invention relates especially to breaking-plows, and especially tothose intended for use in hilly countries, and has for its object toprovide certain improvements in the moldboards with a view of securingincreased eiliciency.

In plowing in a hilly country it is often necessary to plow across theside of a hill with the landside of the plow toward the bottom of thehill, in which case the furrows would have to be turned uphill. lith theplows now in use in plowing across the side of a hill, as justdescribed, the furrow, instead of turning over, will often fall backagain into its original position, making it necessary for the driver tostop his team and turn the furrow over by hand, thus making a great dealof hard work, besides causing much delay.

To the above ends the invention consists of the novel devices andcombinations of devices hereinafter described, and defined in theclaims.

The invention is illustrated in the accompanying drawings, wherein likecharacters indicate like parts throughout both the views.

Referring to the drawings, Figure 1 is a perspective view of theimproved plow looking at the right side thereof with the forward portionof the beam broken away, and Fig. 2 is a perspective view of theimproved plow looking at the right side thereof with the forward portionof the beam broken away.

The numeral 1 indicates the plow, 2 tbe handle-bars, 3 the beam, 4 thestanding colter, and 5 the gage-wheel, which are ci the ordinary orstandard construction.

Rods 6, constituting an adjustable moldboard extension, are pivotallyattached to the moldboard of the plow by short bolts or rivets 7. It maybe here stated that the moldboard extension is, as shown, preferablyconstructed of rods, but, if desired, may be made of a single piece ofmetal. Each rod 6 is pro vided with a laterally-extended stem S, whichworks through a bearing-lug 9, formed on a strap 10, secured to theright-hand handle-bar 2. The projecting end of each stem 8 is riveted toa tie-bar 11.

A latch-lever 12 is pivotally mounted on a brace 13, secured to theinside of handle-bars 2. The lower end of said latch-lever 12 is rovidedwith an arm-like extension 14. A ink 15 connects the lower end of thelever 14 with the central portion of the tie-bar 11. A

per end of the latch-lever 12, has locking engagement with a latch-bar17, secured to the upper portion of the handle-bars 2. The latch-lever12 is provided with a segmental brace 18, struck on a circle from thepivotpoint of said latch-lever 12. Said segmental brace 18 works in agrooved keeper 19, secured to the left-hand handle-bar 2.

As is evident, in ordinary plowing the latch-lever 12 would be set inits eXtreme right-hand position, in which position the moldboardextension would be moved out of working position; but when plowing onthe side of a hill, as previously described, the latch-lever 12 would bemoved toward the lett, and no matter how steep the hill was the furrowwould be positively turned over by said moldboard extension.

The device above described has been put into actual use and has provenextremely etlicient ior the purpose had in view.

What I claim is- 1. The combination with a plow, having an adjustablemoldboard extension, of a lever pivotally supported by the plowhandlebars and connected to said adjustable moldboard extension,substantially as described.

2. The combination with a plow having a moldboard and handle-bars, of anadjustable moldboard extension made up of rods hinged to said moldboard,laterally-extended stems secured to said rods, a lever mounted on saidhandle-bars, and means for connecting said rods to said lever,substantially as described.

3. The combination with a plow having a moldboard and handle-bars,o'l anadjustable moldboard extension made up of rods indespring-pressed latch16, mounted in the up! TOO pendently pivoted to said moldboard,laterlever, substantially as described. f

In testimony whereof I afx my signature n presence of two witnesses.
